CREE SMARTCAST
®
TECHNOLOGY
Cree SmartCast
®
Technology is the most intuitive and easiest to install intelligent light
solution on the market. SmartCast Technology delivers up to 70% energy savings at up
to half the cost of other solutions. Luminaires combine best-in-class light with onboard
sensors and intelligence to deliver a better light experience. Extreme energy productivity,
code compliance and a better light experience without any extra design, installation or
setup work.
CREE TRUEWHITE
®
TECHNOLOGY
A revolutionary way to generate high-quality white light, Cree TrueWhite
®
Technology is
a patented approach that delivers an exclusive combination of 90+ CRI, beautiful light
characteristics, and lifelong color consistency, all while maintaining high luminous efficacy –
a true no compromise solution.
ROOM-SIDE HEAT SINK
An innovative thermal management system designed to maximize cooling effectiveness
by integrating a unique room-side heat sink into the diffusing lens. This breakthrough
design creates a pleasing architectural aesthetic while conducting heat away from LEDs
in a temperature-controlled environment. This enables the LEDs to consistently run
cooler, providing significant boosts to lifetime, efficacy, and color consistency.
CONSTRUCTION & MATERIALS
• Durable 22-gauge steel housing with standard troffer access plate for electrical
installation
• One-piece lower reflector finished with a textured high reflectance white polyester
powder coating creates a comfortable visual transition from the lens to the ceiling
plane
• Includes t-bar clips and holes for mounting support wires (by others)
OPTICAL SYSTEM
• Unique combination of reflective and refractive optical components achieves a
uniform, comfortable appearance while eliminating pixelation and color fringing
• Components work together to optimize distribution, balancing the delivery of high
illuminance levels on horizontal surfaces with an ideal amount of light on walls and
vertical surfaces. This increases the perception of spaciousness
• Diffusing lens integrated with upward-facing LED strip eliminates direct view of LEDs
while lower reflector balances brightness of lens with the ceiling to create a low-glare
high angle appearance

Photometry
CR24-40L-30K BASED ON CESTL REPORT TEST #:
2013-0009
Luminaire photometry has been conducted by a NVLAP accredited testing laboratory in accordance with IESNA LM-79-08. IESNA LM-79-08 specifies the entire luminaire as the source
resulting in a luminaire efficiency of 100%.
